Endangered
Leopard darter
Percina pantherina
Its typical habitat is medium to large streams with rubble and boulder substrate.
The ray-finned fish
Leopard darters rarely exceed three inches (8 cm) in length.
Range and habitat
Historically, the leopard darter was limited to upland, large stream habitats of the Little River drainage in Oklahoma and Arkansas. Currently, scattered populations are found within its historic range. In Oklahoma, it occurs within the Little River drainage (Mountain Fork, Glover, and Little Rivers) in LeFlore, McCurtain, and Pushmataha Counties.
Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
Diet
Spawning occurs in March and April, but may occur as early as February, on gravel-bottomed riffles. Food items include aquatic insects and microcrustaceans.
Spawning occurs on gravel substrates. Even so, the dominant riffle substrate may be gravel, rubble, boulder, and bedrock. It feeds on small invertebrates on the riverbed and spawns mainly in March and April.
In crisis
It is threatened by impoundment, habitat loss and runoff from agricultural activities. It has never been a common species and has been listed as a threatened species in the United States since 1978, and the International Union for Conservation of Nature lists it as a "vulnerable species".
